ARM: Layerscape: consolidate initcalls into one

For Layerscape we have multiple initcalls in the arch directory.
Consolidate these into one initcall which detects the SoC type once
and calls the appropriate init functions. This makes it easier to
add future init steps and also we reduce the number of string
comparisons.
For added value also cpu_is_ls10xx() functions are added which might
become in handy later.
